To all whom it my concerns Be it known thatl, HARRYIS. McCon- MACK, a citizen of the United States, residingin New Rochelle, in the county of VVestchester and State of New York, have 1nvented certain new and useful Improvements in Type-Writing Machines,'-of which the following is a specification. i

This invention relates tothepaper controlling means .oftypewritingmachines, and parti'cularlyto means for feeding original and record sheets when making condensed records. i

Heretofore in writing and recording checks, whose lines of writing are usually yery widely spaced, the objection has arisen that the carbon records made upon-the usual record sheets occupy an excessive amount of room, by reason of such wide line-spacing of the writing on the checks, or on the check sheet, which consists of a succession of check blanks.

The principal object of this invention is to overcome this objection.

In carrying out the invention, '1 provide for advancing or feeding the record'sheet a minimum distance between lines, preferably a distance correspondingwith a single notch in the usual line-space-wheel, while the mul. tiple-check sheet is advanced amuch greater dlstance from one line to the next line of writing thereon. r r

I advancethe record sheetand its carbon While the usual check sheet remains stationary; the movement of the record sheet being effected by the rotation of the platen; and this in turn being effected by the usual linespace lever, which also returns the carriage to begin a new line. Thenahand Wheel is turned, and, by-means of a pair of rollsp connected to the hand wheel by'i'noveine'nt multiplying: gearing, the check sheet i "r idly advanced until the next" ruledlineor blank thereon registers with the usual front platen scale or other device which coincides with the line of writing. This advance of the check sheet is eifected'while the record check; namely, one movement of the line- .platen 2, revolubly mounted by an axle 3 in letter-feeding carriage Said carr a e1" 5 returned to begin F new and; f-pawl operates f spacing lever, which incidentally returns the carriage to begin a new line, and one movement of the checkedjusting hand wheel, to

bring the check -'to register with the rinting line. A' similar operation is ma c after writing the first line, and before beginning the second line on the check. It will therefore be seen that the records of the checks are closely spaced on the record sheet, therein after appear.

In the accompanying drawings, Figure 1 is a sectional elevation of a platen and papenfeeding devices, showing the check and record sheets in position for writing thereon. Fig. 2 is a sectional elevation of the platen, platen frame, and sheet feeding devices constructed in accordance with my improvements; the check sheet being shown released from its feeding devices. F i 3 is a front elevation, illustrating the',re'lat1on of the check to the record sheet, and the man- 30 ner of feeding the latter at its edges. Fig. 11 4 is a sectional view showing the movementmultiplying gearing between the hand wheel and the feed-roli shaft. Fig. 5 is a perspective front view of platen, platen frame, the. Fig. 6 is a plan of the devices at the right hand end of the platen frame.

Types 1 strike on the front side of a a platen frame, comprising ends 4- and. a paper shelf 5; the .iatter curving forwardly around the under side of the platen to form a paper guide 6. "l he platen rests upon a s tim 'bylnieans' erg ratchet inounted'on 'th'e platen Preferably said lever tornsf 'the Wheel only. "a single lever v rh'i ch notch each time that the carriage is returned 7195' to begin a new line of writing, so that the written'lines fall as closely as possible to.-

gether on the record sheet. f

The record sheet 12 is introduced at the rear side of the platen and passed forwardly between the same and the guide 6 and up inv front of the platen, where its side edges are engaged by feed rolls 13 carried upon arms 14, mounted on a rod 15 and adjustable therealong. These rolls are the sole mea'ns for advancing the record sheet; the pressure rolls that usually run upon the bottom of the platen being omitted from the ma chine, so that the record sheet may be advanced Without advancing the check sheet,

and vice versa.

A multiple check sheet 16 is inserted in the machine in the same manner as the record sheet 12, the, latter being provided with the usual front carbon sheet (notshown). The check sheet 16, which consists of a succession of check blanks, is too narow to be caught by the rolls 13, but is led up between the ends of said rolls, and caught by a set of front and rear paired rolls 17, 18, which are located directly overthe printing point in front of the platen. Each of these rolls may consist of several sections, as illustrated. The rear rolls 18 are carried upon 20- a shaft 19 journaledin brackets 20, 21, secured upon the platen frame by screws 22. The forward rolls "17 are carried upon the front ends of a pair of arms 23, 24 hinged at 25 upon said brackets to swing forwardly 25 and downwardly, to separate the rolls 17 from the rolls 18, as at Fig. 2, and permit the introduction of the cheek sheet 16 be tween the same. A draw-spring or. springs 26, extending from the platen frame to the arms 23, 2e, serve either to hold the rolls 17 2 down, as at Fig. 2, or up and against the rolls 18, as at Figsl and 5.

It will be seen that the recordsheet 12 and its carbon may be advanced by merely turning the platen, while the check sheet 16,

whichmcloses the record sheet and thecarbon, remains stationary; and that by turn ing the rolls 17, 18', the check sheet 16 may be advanced while the record sheet 12 and 40 the platen remain stationary.

After the record sheet 12 and its carbon are inserted in the machine, caught beneath the rolls 13, and adjusted to the proper position to receive the'firstline of writing, the checksheet 16 is inserted and slipped around beneath the platen and-ledup between the rolls l7 and 18 at Fig. 2, then the rolls 17 are swun up and back to catch the check sheet 16. hand wheel'27 is then turned. to ad just the check sheet to the printing line; said hand "wheel operating an internal gear 28 by means of a shaft 29, and a pinion 30, in mesh with said. gear, being fixed upon the shaft 19 of the roll or rolls 18, so that (1U1Ckl'l'lOVfii'nent of the check sheet can be easily effected. The check is adjnsted until. the line or blank thereon registers with the usual frontten scale 31 found upon the Underwood and certain other-front-strike machines; the

" top edge of said scale coinciding with the line of writing as seen-at Fig. 3; it, being only necessary'to turn the wheel 27 until the blank line on the check registers with the scale or straight edge 31, when-the writing may begin.

After the completion 'of the line,-which usually consists of the name of the'payee, the operator simply presses the handle 8 to the left, thereby advancing the record sheet- 12 and its carbon 21nd returning the carriage to begin a new line. The operator then turns the hand wheel 27 to register the second line on the check with the scale 31, and then operates the keys to write such second line, which usually consists of the amount of the check. The operator again employs the handle 8 to advance the sheet 12 a single. line and toreturn the carriage, and then turns the handle 27 asutficient distance to bring the first line on the second check into register with the scale or straight edge 31. The operation is repeateduntilthe check sheet 10 is filled. The operator then swings down the roll 17 and Withdraws the check sheet. and inserts afresh one, the record sheet 12 remaining in the machine, and proceeds as before. Thus it will be seen-that records of several check sheets can be condensed upon one record'sheet, and thus a great economy of'spacc and'material is effected. The internal gear 28 is formed with a lmb 32 turning upon a stud 33 projecting outwardly from the bracket 21; and a shaft 34 fixed to the hand wheel 27 is hollowed at its end to fit upon said hub, and is secured thereto. The stud is provided with a screw 35 to hold the gear 2-8 upon the stud.

Having thus-described my invention, I claim:
